| 2 | Tectonic evolution of the Dabieshan orogen: In the view from polyphase deformation of the Beihuaiyang metamorphic zone显示文摘The Beihuaiyang metamorphic zone was formed by the Early Mesozoic collision of the North and South China Blocks. It consisted of the Foziling and Luzhenguan complexes and was thought to have never afforded a deep subduction. A similar feature of the deformation in the Dabieshan UHP metamorphic rocks implies that these different tectonic units share the same geodynamic background. The early stage of deformation can be preserved on account of their relatively shallower subduction than that for UHP rocks. On the basis of an analysis of the geo- logical structure and geochronological results, five deformational stages have been recognized: a D1-Early compressional deformation which represents the continental subduction; a D2-Early exhumation deformation producing a syn-convergence exhumation; a D3-Main deformation, represented by an exhumation deformation with Late Triassic age; a D4-Doming and its margin extensional gravity collapse deformation and finally a D5-regional extensional deformation of Cretaceous that was mostly introduced by the migmatization and plutonism. | LIN Wei1, 2, Faure Michel3, WANG Qingchen1 & Arnaud Nicolas4 1.

| 4 | OXIDATION OF A TWO-PHASE Cu-75Cr ALLOY IN AIRAT 700-900℃显示文摘The cormsion in air of a two-phase Cu-75Cr alloy was studied at 700-900℃. Thealloy cormded nearly parabolically at 700-800℃, but at 900℃ its instantaneousparabolic mte constant decreased with time. The scales were complex and consistedof an outermost layer of copper oxide generally followed bg a layer of the double ox-ide Cu2 Cr2 O4 sometimes containing particles of unoxidized chromium surmunded bya chromia layer. An innermost layer of chromia was also observed in some cases.Finally metallic copper was al8o frequently mixed with chromia particles. No Cr de-pletion was observed in the alloy close to the inteffoce with the scale. In any case,this alloy was not able to form an exclusive continuous protective chromia layer. Thespecial cormsion behavior Of this alloy is typical of two-phase binary systems with alange solubility gaP in which the outwaof dthesion fiux of the most-reactive componentin the alloy is strongly reduced and may be inswncient to fOrm a protective externallayer of the cormsponding oxide. In paTticular, the presence of particles of Cr withina double oxide layer is very unusual and is allowed only for the kinetic reason. | F. Gesmundo Y Niu F. Vianiand D.L.

| 8 | Friction Characteristics of Mechanical Seals with Laser-textured Seal Faces显示文摘Heat generated by friction between faces of mechanica l seals is a major factor that causes deterioration of the seals and shortens th eir service life. Excessive temperature rise can greatly alter the seal geometry and vaporize the sealing fluid, resulting in friction of boundary lubrication. These effects on face seals usually lead to excessive leakage and ultimately ren der the seal inoperable. In order to maintain the reliability of seals, high fri ction and unwanted wear must be avoided. Using the laser-texturing process to produce regular micro-surface structures is a fast and convenient technique compared to some more conventional etching or erosion technique currently used by the seal industry for various grooved face seals. Indeed, by using a pulse laser, better control is obtained on the geometr y, size and pore ratio of seal rings made of metallic or ceramic materials. In t his study, seal rings are made of silicon carbide and carbon. Mating faces of th e rings are polished and only silicon carbide rings are laser-textured. The las er texturing can be controlled to produce spherical pores at selected diameters, depths and pore ratio. The textured rings are then super-polished to remove th e bulges formed on the pores rims. After this process the average pore diameter, pore depth and pore ratio reach the predetermined parameter. Some untextured ri ngs are also treated to the same surface roughness and served as a reference for comparison of the textured rings. A special test rig is used to simulate a mech anical seal system and to measure the effect of the laser texturing on friction and seal performance. Tests are performed at various rotational speeds and vario us axial loads. Compared with the conventional mechanical seals, temperature rise, friction torq ue and friction coefficient of mechanical seals with laser-textured seal faces are much lower. These preliminary results show the potential of improving fricti on performance and increasing seal life with laser-textured seal faces. | YU Xin-qi 1,2, HE Song 1, CAI Ren-ling 1 (1.

| 9 | 印度尼西亚竹子栽培与利用(英文)显示文摘竹子在印度尼西亚广为使用,尤其是在乡村,因为它生长快,易采伐,使用方便,性能好。本文“印度尼西亚竹子栽培与利用”报道了目前印尼竹子的栽培、加工及研究、开发方面的进展。在印尼,许多竹种的栽植历史已有好几百年。传统的繁殖方法是用秆及鞭,而其它栽培繁殖方法尚处于试验阶段。可以这样说,印尼的竹子栽培研究尚处于早期的开拓时期。竹子在印尼有许多用途,如建筑材料,家具,墙,篮子,家庭器具,造纸,篱笆,手工艺品,农具,乐器及食品。目前,印尼竹子加工利用技术研究正处于全面的开发阶段。今后竹子作为工业用材的前景非常广阔,然而也存在一些问题。为提高竹子对乡村社会的贡献,促进竹子工业利用的发展,我们应该对竹子的生物学特性,营林,社会经济,新产品设计、开发,防蛀防霉,精加工等等进行更深入的研究。 | Subyakto and Bambang Subiyanto(R&D Centre for Applied Physics—Indonesia Institute of Sciences Puspiptek Serpong 15310,Indonesia)Sandra A.Azis(Department of Agronomy,Bogor Agricultural University, Bogor,Indonesia) | 1997 | 竹子研究汇刊1997，16，2： | 8 |
| 10 | Structure and Property of Bamboo Fiber显示文摘The chemical composition, fiber characteristics, crystalline structure, mechanical properties and thermal behavior of the five species of bamboo (Phyllostachys edulis cv.Pachyloe, Bambusa tootisk, Arundinaia amabilis, B.vulgaris cv. Vittata, and Dendrocalamus affinis) were studied with IR, X-ray, DSC and chemical analyses. The results indicated that the benzene-ethanol extractive content of bamboo was higher than that of wood, the content of lignin and the content of pentosan were 19.1% - 25.3% and 14.9% - 22.6%, respectively. Except for Ph. edulis cv. Pachyloe, the cellulose content in the other 4 species was over 50%. The average length of fiber of D. affinis was the longest (1.861 mm). The length/ width ratio of bamboo fiber was also higher than that of wood, and it was the highest for B.tootisk, which reached 142. The results of IR and X-ray confirmed that crystalline structure of bamboo fibers was cellulose, and A. amabilis had the highest crystallinity index. The differential thermal analysis (DSC) can be one of the methods to identify various fiber materials. After steam explosive pretreatment, cellulose content of D. affinis had increased from 50.5% to 69.2%, the crystallinity index had increased and the breaking tenacity of bamboo fibers was suitable for producing textile products, indicating that steam explosion is an useful pretreatment for bamboo fibers made into composite materials and textiles. | JIANG Jianxin1 YANG Zhongkai2 ZHU Liwei1 SHI Limin2 YAN Lijie1 1.

| 12 | Effects of disinhibition on spatiotemporal pattern of neuronal first recruitment in neuronal networks显示文摘The propagation of neuronal activities is a key feature to understanding information processing in networks. The analysis based on first-spikes of bursts in turn plays an important role in the research of neuronal activity propagation. Our focus here is to investigate how spatiotemporal patterns of neuronal first-spikes are affected by disinhibition. Multi-electrode arrays were used to record stimulation-evoked bursts of multiple neurons in randomly cultured neuronal networks. Both the precise timing of and the rank relationships between first-spikes were analyzed. Compared with evoked bursts in the network's native state, the precise first-spike latencies in its dis-inhibited state are more consistent and the propagation of its bursting activities is much faster. Additional points of interest are that disinhibited neuronal networks can be evoked to generate stable and distinguishable neuronal first recruitment spatiotemporal patterns specific to the stimulation site, and that the disinhibition may cause the original spatiotemporal patterns to change in a heterogeneous manner with regards to different propagation pathways. | Liangbin Pana,b,c,1, Xindong Songa,b,c,1, Guangxin Xiang a,b,c, Jing Zhua,b,c, Jing Cheng a,b,c,d,a Medical Systems Biology Research Center, Tsinghua University School of Medicine, Beijing 100084, China b Department of Biological Sciences and Biotechnology, Tsinghua University, Beijing 100084, China c National Engineering Research Center for Beijing Biochip Technology, 18 Life Science Parkway, Beijing 102206, China d State Key Laboratory of Biomembrane and Membrane Biotechnology, Tsinghua University, Beijing 100084, China | 2009 | Progress in Natural Science:Materials International2009，19，5： | 6 |
| 13 | Preliminary discussion of low-salinity hydrothermal fluid mineralization显示文摘REVIEWING the history of the geology of mineral deposits, we may find that in the first fifty years of thetwentieth century the magmatic-hydrothermal theory of ore deposition was the most prevalent, whichgave impetus to the development of the geology of mineral deposits. In the 1960s, the drilling of theSalton Sea geothermal field, California, the United States, and discovery and study of the Red Sea seafloor hot brines and large amounts of metal sulfides removed therefrom led to the rise of the brine theory ofmineral deposition, thus elucidating the origin of massive metal sulfides and promoted the discoveryand exploration of metal deposits. After the 1970s and the 1980s, through a study of the hydrothermal ore fluids of modern hotsprings. geologists came to realize that there exist low-salinity hydrothermal ore fluids other than | ZHENG Mianping R & D Center of Saline Lake and Epithermal Deposits, Chinese Academy of Geological Sciences, Beijing 100037, China | 1999 | Chinese Science Bulletin1999，44，S2： | 5 |

| 19 | The influence of impurity on the critical thickness of the CeO_2 buffer layer for coated conductors显示文摘The lattice parameters, band structure, density of state and elastic constant of RE-doped CeO2 (RE=Sm, Gd, Dy), the buffer material for coated HTS conductors, are calculated using the plane-wave method with pseudopotentials based on the density functional theory (DFT) of first-principle. The rule and mechanism of the effect of rare earth impurity on the critical thickness of the CeO2 buffer layer are investigated. It is found that, in the range of the calculation, the changes of the lattice volume V and elastic constant E of CeO2 with the impurity are mainly determined by the increased electrons ne of the system. The relationship of the elastic constant E and increased electrons ne is established. It is indicated that the critical thickness of the CeO2 single buffer layer doped with Sm, Gd, and Dy may be enhanced by 22%, 43% and 33%, respectively. | PAN Min1, HUANG Zheng2, MA HuanFeng2, QIANG WeiRong2, WEI LianFu1, WANG Long2 & ZHAO Yong1,3 1 Key Laboratory of Magnetic Levitation Technologies and Maglev Trains (Ministry of Education of China), Superconductivity R&D Center (SRDC), Southwest Jiaotong University, Chengdu 610031, China 2 School of Physical Science and Technology, Southwest Jiaotong University, Chengdu 610031, China 3 Superconductivity Research Group, School of Materials Science and Engineering, University of New South Wale, Sydney, 2052 NSW, Australia | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，7： | 3 |
| 20 | The effects of K^+ growth conditions on the accumulation of cesium by the bacterium Thermus sp. TibetanG6显示文摘The accumulation of cesium by the bacterium Thermus sp. TibetanG6 was examined under different K+ growth conditions. The effects of external pH and Na+ on the accumulation of ce-sium were also studied, and the mechanism involved was discussed. K+ regimes played an important role in the accumulation of cesium by the strain TibetanG6. The quantity of cesium accumulated (24 h) was much higher in K+-deficient regime than that in K+-sufficient regime. The pH and Na+ had different effects on the accumulation of cesium in the two K+ regimes. IR spectra analyses indicated that the biosorption is a process of homeostasis with cesium initially accumulated on the cell wall. | WANG Hailei1,2,3, KONG Fanjing1,2,3 & ZHENG Mianping1,2,3 1.
